isaac newton laws of motion
The first law- of a moving object will continue moving in a straight line at the constant speed, and a stationary object and will remain at rest, unless acted on by an unbalanced force.The second law- the acceleration produced on the body by force is proportional to the magnitude of the force and is inversely proportional to the mass of the object. Force = mass x acceleration. Third law- for every action there is an equal and opposite reaction
